Manufacture of Organic Electroluminescence Device Comparative Example 1

Trichloroethylene, acetone, ethanol, and distilled water weresequentially used to ultrasonically wash a transparent electrode ITOthin film obtained from glass for OLED (manufactured by Samsung-CorningCo., Ltd.) for each of 5 minutes, and then the ITO thin film was placedin isopropanol, stored, and then used.

Next, the ITO substrate was installed in a vacuum deposition device.Sequentially, in a vacuum chamber,4,4′,4″-tris(N,N-(2-naphthyl)-phenylamino)triphenyl amine (2-TNATA) wasvacuum deposited to a thickness of 600 Å on the ITO, thereby forming ahole injection layer.

Thereafter, a hole transporting layer was formed by depositingN,N′-bis(α-naphthyl)-N,N′-diphenyl-4,4′-diamine (NPB) under vacuum to athickness of 300 Å on the hole injection layer.

And then, a light emitting layer having a thickness of 200 Å wasdeposited under vacuum on the hole transporting layer by setting a bluelight emitting host material H1 and a blue light emitting dopantmaterial D1 at a ratio of 95:5.

Subsequently, the compound of the following structural formula E1 wasdeposited to a thickness of 300 Å on the light emitting layer, therebyforming an electron transporting layer.

Thereafter, lithium fluoride (LiF) was deposited to a thickness of 10 Åas an electron injection layer on the electron transporting layer, andAl was deposited to a thickness of 1,000 Å on the electron injectionlayer to form a negative electrode, thereby manufacturing an OLED.

Meanwhile, all the organic compounds required for manufacturing an OLEDwere subjected to vacuum sublimed purification under 10⁻⁶ to 10⁻⁸ torrfor each material, and used for the manufacture of the OLED.

Examples 1 to 145

An organic electroluminescence device was manufactured in the samemanner as in Comparative Example 1, except that the compound of thefollowing Table 3 was used instead of E1 used when an electrontransporting layer was formed in Comparative Example 1.

[Experimental Example] Evaluation of Organic Electroluminescence Device

For each of the organic electroluminescence devices manufactured inComparative Examples 1 and Examples 1 to 145, the driving voltage, theefficiency, the color coordinate, and the service life were measured ata light emitting brightness of 700 cd/m² and evaluated, and the resultsare shown in the following Table 3. In this case, the service life wasmeasured by using M6000PMX manufactured by Mac Science Co., Ltd.
